Error while downloading

[pietra]

So i recently installed Windows 7 then i installed the most recent Utorrent version 2.04. While i am downloading sometimes not always i get the following error:

The requested operation can not be performed with an open section mapped by the user.

If i start the download again it continues with no problems.

I would like to know what the problem is and how to solve it?

Kapersky or AVG?

Kapersky but the firewall is allowing utorrent to connect and only happens to a few torrents but before i formatted the computer i used to download stuff from the same sites and had no issues and the AV was the same only the 2010 version instead of the 2011 now .
